W. A. Puckner, Secretary. According to the Hemo-Therapin Laboratories of New York City: “Hemo-Therapin is a combination of highly refined creosols and phenols (which have been detoxicated by special processes) with salts of iron, potassium, sodium, phosphorus and calcium in minute but physiologic proportions--the solution as a whole being designed to approximately closely in various fundamental details the chemistry of the blood.” No statement is made as to the quantities of the several ingredients, nor is any information given as to the identity of the “creosols” and “phenols,” nor the nature of the processes whereby these are “detoxicated.” It is further claimed that it is: “... The composite character of Hemo-Therapin, the relative proportion and balance of its several ingredients, and the action of the compound as a whole, to which its potency is due.” And it is suggested that: “It will be apparent that the ingredients which enter into the composition of Hemo-Therapin, a remedy used intravenously exclusively, have been selected with the utmost care with the object of assuring not only maximum therapeutic potency but also _absolute safety and freedom from all dangers of toxic or other unpleasant or harmful action_.” [Italics in the original.] The advertising does not explain, however, why the complex preparation should be therapeutically efficient or why the intravenous administration of this mixture should be absolutely safe and free from toxic or harmful action. Of the origin of Hemo-Therapin it is said: “For many years Dr. E. B. Witte, a prominent physician of Trenton, N. J. [apparently owner of the Hemo-Therapin Laboratories] has devoted himself to the study of the blood. As a result of his researches, he early determined that when the blood is close to normal standards, the body is well nourished, the natural waste products are properly eliminated, an effective resistance is offered to the invasion of pathogenic bacteria, and the various functions of the body are kept normally active. But when, for one reason or another, the blood falls away from normal standards, the nutrition of the body suffers, the elimination of waste products is impaired, the resistance to germ attack is weakened, and the various functions of the body become sadly deranged and perverted. In other words, instead of the physiologic processes of the body being normally active, as soon as the blood is depreciated, they become depressed or deranged, with a loss of the physiologic harmony or equilibrium that constitutes a state of health.
